SY Multi-Function Watt-Hour Meter Test Device

Single / Three-phase electric energy meter inspection device is an electronic program-controlled single-phase electric energy meter inspection device carefully researched and developed in accordance with the requirements of relevant standards and regulations. It is suitable for the inspection of various single-phase electric energy meters of class 0.2 and below. It has a simple and beautiful appearance, exquisite craftsmanship, complete functions and excellent performance.

 

Product characteristics

 

1. Reasonable design and beautiful appearance. The device hanging table frame and table body frame are made of special aluminum alloy materials, and the table top is made of fire-proof and heat-resistant fiber materials. The whole device has soft colors, coordinated proportions, and reliable structure. Exquisite craftsmanship, beautiful appearance.

2. Dedicated keyboard operation and PC operation coexist, easy to use. This device is equipped with a keyboard, the keyboard comes with a liquid crystal display, and the working status of the device is clear at a glance. The operation is easy and free. The PC control software has clear levels, beautiful interface, and flexible and convenient use.

3. High degree of automation. When verifying the electric energy meter, only need to manually participate in the watch, adjust the photoelectric sampler, and correctly design the parameters of the meter, all the verification items (including warm-up, creep test, start-up test, standard deviation determination, and basic error determination) ) It is automatically controlled by the PC and completed at one time. The calibration procedure can be in accordance with national regulations or can be customized by the user.

4. The photoelectric sampler can realize three-dimensional adjustment, and can sample the turntable signal of the rotary electric energy meter. It can also receive the stroboscopic signal of the electronic energy meter.

5. The error processing system can receive the photoelectric sampler signal, the output pulse of the mounted electronic meter and the high-frequency pulse signal of the standard electric energy meter, etc.

6. Energy meters of the same type (phase line, rated voltage, and calibrated current are the same) and different constants can be calibrated at the same time (limited to three constants).

7. It can test the communication function, demand error, clock error, and time switching error of the 485 port of the multifunctional electric energy meter.

8. The black mark of the turntable of the rotary electric energy meter can be automatically positioned, which is convenient for diving (starting) testing.

 

9. 2 to 21 harmonics can be superimposed on the power frequency fundamental wave, and the amplitude and phase of the harmonics can be set as required. It can also perform harmonic analysis on the output and draw the waveform.

 

10. It can automatically test the voltage, current, power stability and three-phase total power stability of each unit, and can automatically give the comparison error of the device monitoring instrument and the three-phase asymmetry index of the output power.

 

11. The device has high stability, good reliability and high output power. The voltage (current) loop can carry loads of any nature.

 

12. The device has complete fault detection, positioning, protection and alarm functions to avoid damage to the device due to man-made wiring or operation errors.

 

13. The PC management software also has functions such as complete report printing, mathematical statistics and asset maintenance.

 

14. Configure multiple pulse inputs, active positive and negative, four-quadrant reactive signals, one-time wiring, software control, and improve efficiency.

 

15. Configure multi-serial communication board, parallel 485 communication, improve work efficiency.
